Pin	Connection	Comments
1	Preset Tally A	Preset tally output
2	Reference Video Valid	1: Valid;	0: Ref video error
3	Dolby E Encoding Valid	1: Valid;	0: Encoding error
4	System Operational	1: Functional	0: Failed
5	Fault	1: Functional	0: Hardware Fault
6	Preset Tally B	Preset tally output
7	Preset Ctrl A	Preset control input
8	Preset Ctrl B	Preset control input
9	Ground	—

Pins 1 and 6 Presets 1–3 generate corresponding outputs on the status port that can be used to indicate selection of a preset via the status port, serial remote port (in future versions), or the front panel.

High	High	Other or no preset

Pins 2-5 These indicate the current condition of the unit. A “1” corresponds to a high level on the corresponding pin.

Pins 7-8 The two inputs on pins 7 and 8 select among the first three (of eight) presets stored in the DP571. The inputs are normally high (internal pull- up) and trigger a preset recall by sensing a momentary high-to-low transition.
